Cosa: Reservoir, Cistern, and Bath Complex 3D Model
IMPORTANT: Use the annotations to experience the underground portion of the model!
The 2015 archaeological dig at the Ancient Roman colony of Cosa continued exploration of the site’s Bath Complex. Because the ancient city had no springs, and no apparent way of getting a steady supply of fresh water other than by collecting rainfall, the role of reservoirs, cisterns, and holding tanks cannot be underestimated.
Shown here are the 2015 trenches at the bath complex, and the large reservoir, situated directly across the ancient street, now hidden under soil.
The large reservoir is connected to a cistern by a cuniculus, which runs under the street, and would have channeled collected water to a “water tower” at the bath complex, from which fresh water could be drawn as needed.
